RULE.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed April 12. 1907. Serial No. 367,879.

To all whom it may concern:

Be it known that I, HENRY JErrnEYs, a citizen of the United States ofAmerica, residing at West Salisbury, in the county of Somerset and Stateof Pennsylvania, have invented certain new and useful- Improvements inRules, of which. the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to rules, and the invention has for its object toprovide a rule with novel means for steadying and positioning one end ofthe rule. in order that an accurate measurement can be obtained by therule.

Another objectof this invention is to construct a rule or measuringdevice with lugs and ridges at its one end, whereby the end of the rulecan be firmly held in engagement with an object and while a measurementis being determined.

With the above and other objects in view, which will more readily appearas the invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be hereinaftermore fully described and then specifically pointed out in the appendedclaims.

Referring to the drawing forming part of this specification, likenumerals of reference designate corresponding parts throughout theseveral views, in which:

Figure 1 is an elevation of one side of my improved rule, Fig. 2 is anelevation of the opposite side, Fig. 3 is an edge view of a portion ofthe rule illustrating the manner in which the same is used to obtain anoutside measurement, Fig. 4 is a similar View illustrating the manner ofobtaining an inside measurement, Fig. 5 is a similar view illustratingthe manner of obtaining the inner diameter of a tube or pipe, Fig. 6 isa perspective view of the end of a rule constructed in accordance withmy invention.

' In the accompanying drawings, I have illustrated an ordinary rule 1having graduations 2 upon both sides thereof, said rule beingconstructed of wood, celluloid, metal or any suitable durable material.I I

My invention resides in locating near the beveled end 3 of the rule, twoside ridges 4 and 5 having shoulders 6 and 7 respectively, saidshoulders being oppositely disposed with relation to one another.

The edges of the rule are provided with integral beveled lugs 8 and 9having shoulders 10 and 11 respectively. The faces of the shoulders 7and 10 aline with each other and with the zero graduation or beginning ipoint of the rule scale upon one side of the rule as shown in Fig. l,and the opposite facing shoulders 6 and 11 are in alinement with eachother and with the beginning point of the graduations upon the oppositeside of the rule (Fig. 2). All of the described shoulders form rightangles at their line of meeting with the rule surfaces,

thus enabling my rule to be employed as a T-square and straight edge. Tofurther facilitate its use the edges of my rule may also he graduated.

The manner of using my improved,rule is illustrated in Figs. 3, 4 and 5.Assuming that it is desired to obtain llllWlClllll of a piece ofmaterial (see Fig. 3), the ridge 5 is placed in engagement with one sideof the material, the shoulder 7 of said ridge bearing upon the side ofthe material while the rule lies upon the edge thereof. terial wherebyan accurate measurementwill be readily obtained.

When it is desired to ascertain the distance from one piece of materialto another piece of material or object, the shoulder 6 of the ridge 4 isplaced in engagement with the side of the piece of material, the end ofthe rule overlying the edge of the material to steady the rule and holdthe same in approximately a horizontal plane whereby the scale shown inFig. 2 may be read to ascertain a correct measurement.

To obtain'the diameter of a pipe or tube (see Fig. 5), the shoulder 11of the lug 9 is placed in engagement with the inner side of a tube orpipe, the edge of the rule bearing against the end of the pipe. It willthus be seen that an accurate measurement can be made in order todetermine the interior diameter of a pipe. The outer diameter can beeasily ascertained by placing the shoulder 10 of the lug 8 upon theouter edge of the pipe at the end thereof.

My invention facilitates the rapid manipulation of a rule whendetermining various measurements, and the improvement can be readilyembodied upon rules or measuring devices of various designs.

What I claim and desire to secure by Letters Patent, is

A rule having graduated sides, ridges carried by the sides of said ruleand spaced from one end thereof, and having oppositely disposedshoulders, and lugs carried by the edges of said rule adjacent to saidridges and having shoulders oppositely disposed at right angles to therule edges, the faces of each pair of similarly disposed shouldersalining with each other and with the zero graduation upon opposite sidesof the rule.

In testimony whereof I aifix my signature in the presence of twowitnesses.
